I woke up this morning to find one of my julii/tri cories dead. I think he was killed by the betta as there was a large discoloration behind the gill cover. The other julii/tri seems to be free of marks, but it is just swimming around in the middle of the tank. The panda and the skunk are behaving normally, but I am wondering if maybe the julii/tri could be lonely ?
